It controls the motor's significant systems, including the engine, ignition, fuel injection, and charging system. The ECM uses inputs from sensors throughout the motor to monitor operating conditions and adjust the various techniques as needed. The ECM also stores diagnostic codes that can be used to troubleshoot problems with the engine.
